rsevents-extra is a utility crate with a number of useful synchronization "primitives" built on
top of (and therefore, at a higher level then)
rsevents-extra is a community project, feel free to contribute additional synchronization objects
to this crate!
Please refer to the
rsevents README and
documentation to learn more about
rsevents. At its core,
rsevents is a low-level signalling and synchronization library, mimicking the behavior of the
WIN32 auto- and manual-reset events, and can be useful to add lightweight and performant
synchronization to programs where the needs do not strictly align with the concepts of critical
Utility events included in this crate
This crate contains implementations of the following events:
- Countdown Event
A countdown event is a useful synchronization tool for spawning tasks and checking on their
completion status. A
CountdownEvent object is instantiated with a count, and upon each call to
CountdownEvent::tick(), the internal count is decremented. A waiter can call
CountdownEvent::wait() (or any of the other wait routines exposed by the
Awaitable trait) to
block (efficiently) until the countdown reaches zero. Once the internal countdown reaches zero, the
event becomes set and waiters are woken/notified.
